To allwhomitmaycmwem:

Be it known that I, CHARLES E. GODLEY, a citizen of the United States, and-residing atDetroit, in the county of Wayne and State 6 of Michigan, have invented a new and ,Im-

proved Signal Lamp, of which the following is a specification j g This invention relates to the type of lamps disclosed in my pending application Serial Number 570,670, June 24, 1922, and the object of the present-invention is to provide cheap and efficient means whereby the lenses of lampsof this character may be resiliently su ported.

is invention consists in a resilient packin sheet of-thick paper board, cork, leather, rubber or other resilient material, fitting between the edges of the lenses and a rigid backing and also fitting within the door or lens ring of the lamp, the sheet being apertured so as to offer no objectionable obstruction to the light rays. It also consists in means attached to. the packingsheet and extending into a notch in the periphery of a corrugated circular lens to prevent the lens from turning. It further consists in'the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the accompanying drawing, Fig. 1, is

a front elevation of this improved lamp. Fig. 2 is a section on the line 2-2 of Fig. 1 on a larger scale. Fi 3 is arear elevation of the lamp door an the packing sheet in position therein.

Similar reference characters refer to like parts throughout the several views.

As described in my former application,

this lamp comprises a body having a back 1 and sides 2, which sides merge into the semi-cylindrical to 4 and bottom 5. The front edge of the ody is bent out into the inclined flange 7 and the terminal flange 8 which constitutes the edge of the body. An

opening 9 may be'cut in the bottom 5 to permit light to. fall on a, license plate, this opening being closed by the sheet 10 of celluloid. I a

A cylindrical shell 14 having a back 15 and a radial front flange 16 is mounted in the body, and in it is mounted a reflector 17. A. connector tube 18 is secured in the shell 14 and supports the two light bulbs upper ortion o and 20, 'theconnector tube being formed wlth an opening 22-t0 permit the introductionof contacts on the end of a conductor to carry current'to the contacts 23 on the bases of these lamp bulbs... These details are fully shown in the co-pending application and are; there'forehere' omitted.

H 'The upper lens. 25 is circular withacircular shoulder 26on its inner side and vert calcorrug'ations 24:,(Fig. 1) on its outer side. A notch 27 is provided at any convenlent point. The lower lens 28 is lunate and preferably domed and its upper edge 29 fitsthe lens 25. The lens ring or. door has a circular upper portion 31 to receive the upper lens and a circular lower portion 32 which extends around the lower lens, these two portions being connected by the straight portions 33.

The central transverse portion 34 of the door is substantially semi-circular in crosssection, as shown in Fig. 2, while .in the outer edge portions the transverse curvature is continued until the rearedge 35 of the doorwhich contacts with the edge .8 of thebody is within the greatestdimensions of the door at 36. I i

It might be said that the cross section of the edge of the door is that of one half of an ellipse cut diagonally. Mounted within the door to serve as a cushion for the lenses is a sheet 37 of paper board, cork, rubber or other resilient material and this sheet is made to fit within the largest diameter of i the door, as shown in Fig. 2. This sheet is apertured as shown in Fig. 3 and when sprung into position prevents the lenses-from falling out of the lamp door. Y It is held in position against the radial flange 16 of the shell and against the front edge 8 of the-body by the pressure of the lenses and of the door through the action of the screws 40 which aredescribed in my co-pending application.

In order to prevent the lens 25 from turning, which is desirable when the lens is. corrugated. in order to spread the rays of light laterally onthe roadway'as the vehicle on may. be attached to the the packing 37. This clip prefer'a 1y comprises a tongue 42fwhich extends into the'notch 27 in the lens and two 05 flanges 43 and 44 between which the packing small metal clip is gripped. Small teeth may be formed on these flanges 43Land 4A: to firmly secure the clip'in position onthe packing.

I claim:

1. In a signal lamp, the combination of a body having cylindrical ends, a circular lens, a lunate lens in the same plane therewith and having an edge fitting the edge of the first lens, a door to receive said lenses and having a circumferential portion whose cross section is substantially one half of an ellipse cut diagonally, the inner edge of said portion engaging the lenses and'the outer edge engaging the outer edge of the lamp body, said door having a curved transverse portion extending over the adjacent edges of the two lenses,-an' apertured packing sheet fitting within the door and covering the edges" of said lenses, and means to press the :0 door, lenses and packing toward the body.

2. In a lamp, the combination "of a body,

a lens at one end thereof and in its edge, means to secure body, a packing sheet between the lens and body, and a clip secured to the packing sheet and extendlng into said notch in the sheet of resilient material between the edge of the lens and the and-contacting with the body at the inner edge of the flange thereon andwith the outwardlybent edge of said flange.
